投影机放置位置

决定投影机应放置何处时,请考虑屏幕的尺寸和形状、电源插座的位置以及 投影机与其他设备的距离。=以下列出一些普遍准则:

·将投影机放在平整的表面上,与屏幕成直角。= (使用标准镜头的)投影 机与投影屏幕的距离,必须至少=P=英尺 (MKV=米)。

·(除非购买加长连接线,否则)投影机与电源的距离不应超过=NM=英尺 (P=米),与视频设备的距离不应超过=S=英尺 (NKU=米)。=为了保证有适 当空间可够及连接线,投影机应距离墙壁或其它物体至少=S=英寸

MKNR=米)。

·如果要将投影机安装在天花板上,请参阅随天花吊顶装置附带的安装指 南中的详细信息。 如果要使图像上下颠倒,请参见第 36 页上的 吊顶 安装。 我们建议使用经核准采用的天花吊顶装置。 天花吊顶装置单独 出售。有关的详细信息,请参见此投影机随带的附件产品目录或访问我 们的网站。

·将投影机放在距离屏幕合适的位置处。=投影机镜头与屏幕的距离、缩放 比例设置和视频格式等因素决定投影图像的大小。=关于不同距离时投影 图像尺寸信息,请参见第 QQ 上的 投影图像尺寸 Ò=

·对于投影机随带的标准镜头,图像以给定角度投射。=但是,镜头移位功 能使图像位移为可变量。=当投影机处于=QWP=模式 (缺省模式)时,图像 位移在=NMWM=比率时为=NMMB=这表示图像的高度若为=NM=英尺,所有= NM=英尺图像将出现在镜头中心之上。=

·当镜头移位为=NWN=比率时,此图像位移为=RMB=这表示图像的高度若为= NM=英尺,图像的底线将在镜头中心之下=R=英尺处。=

·关于可选用镜头图像位移的信息,请参见第 QQ 上的 投影图像尺寸 Ò=
